PROBLEM TO BE SOLVED: To provide the structure of electronic equipment with a solar cell that achieves generation by the solar cell without technical and design restriction in a display part in various electronic equipment with the display part such as an electronic watch with the solar cell. SOLUTION: An opening hole 10a being extended in the rotation direction of a pointer is punched on the side surface part of the three o'clock direction of a drum 10, and the external part of the drum 10 communicates with internal part for accommodating a movement 11. A light-guide material 21 is fixed inside the opening hole 10a. The external side end face 21a constitutes an incidence window part, and outside light being taken from the incidence window part is transmitted through the inside of the light-guide material 21 and is discharged from an internal side end face 21b facing the inside of the drum 10. A solar cell 22 is arranged at a position facing the internal side end face 21d of the light-guide material 21 in the inside space of the drum 10, and a light reception surface 22a of the solar cell 22 opposes the internal side end face 21b. |
